How it works

From the US prescribing label for the same active substance (ZILBRYSQ). It describes the substance, not this exact product.

Zilucoplan binds to the complement protein C5 and inhibits its cleavage to C5a and C5b, preventing the generation of the terminal complement complex, C5b-9.

The precise mechanism by which zilucoplan exerts its therapeutic effect in generalized myasthenia gravis is unknown but is presumed to involve reduction of C5b-9 deposition at the neuromuscular junction.
